Pygmy Corydoras Care Guide
Corydoras pygmaeus · Freshwater Fish

What Pygmy Corydoras look like
Corydoras pygmaeus, commonly known as the Pygmy Corydoras, exhibits a diminutive, laterally compressed body that typically reaches a maximum adult size of 1.5 inches (approximately 4 cm). This species displays sexual dimorphism, with males being slightly smaller and more slender than females, which tend to have a fuller abdomen, especially when gravid. The Pygmy Corydoras is characterized by its distinctive pattern of dark spots on a pale background, which serves as a form of camouflage against the substrate. Notable morphological features include a well-developed adipose fin, a broad, rounded caudal fin, and a series of bony plates along the lateral line, providing protection against predators. The dentition is adapted for its omnivorous diet, featuring small, bristle-like teeth that aid in foraging for food in the substrate.
Behavior & temperament
In terms of behavior, Corydoras pygmaeus is a social species that thrives in groups, exhibiting a schooling behavior that enhances its safety in the wild. These fish are primarily benthic dwellers, foraging along the substrate for food while remaining in the lower strata of the water column. They are known to be peaceful and non-aggressive, often cohabiting with other small fish species. During breeding, Pygmy Corydoras engage in egg scattering, where females release eggs onto the substrate, and males fertilize them shortly thereafter. This species exhibits a calm temperament, making them suitable for community tanks.
Diet & feeding
In their natural habitat, Pygmy Corydoras are omnivorous, feeding on a varied diet that includes detritus, small invertebrates, and plant matter. In captivity, they require a balanced diet consisting of high-quality flake food, sinking pellets, and occasional live or frozen foods such as daphnia or brine shrimp to ensure optimal health.
Behind the name
Corydoras (from Greek: 'korys' meaning helmet; 'doras' meaning skin) refers to the armored nature of the fish, while pygmaeus (from Greek: 'pygmaios' meaning dwarf) denotes its small size.
